UC2909MDWREP

Overview

The UC2909MDWREP is a switch-mode lead-acid battery charger manufactured by Texas Instruments. It operates within a supply voltage range of up to 40 V and delivers an output current of 2 A with a maximum output voltage of 20 V. The component is housed in a 20-pin SOIC package designed for surface-mount technology. It supports an extended industrial temperature range from -55 °C to +125 °C, ensuring reliability in demanding environments.

Feature Summary

Integrated switch-mode control architecture optimized for lead-acid battery charging applications
Capable of delivering regulated charging currents suitable for automotive and industrial power systems
Designed for high-temperature operation to withstand harsh environmental conditions

Applications

Lead-acid battery management in automotive systems
Industrial uninterruptible power supply (UPS) units
Telecommunications backup power systems

Procurement Notes

Verify the specific suffix 'MDWREP' against the official Texas Instruments datasheet to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure that the SOIC-20 footprint matches your PCB design guidelines. Confirm RoHS compliance status directly with the manufacturer documentation prior to final procurement decisions.

Selection Notes

Select this component when designing systems requiring dedicated switch-mode regulation for lead-acid batteries. The wide operating temperature range makes it suitable for automotive under-hood or industrial outdoor installations. Compare thermal performance requirements against the SOIC-20 package capabilities to ensure adequate heat dissipation without additional heatsinking.

Part Context

This part belongs to the UC2909 series of battery chargers from Texas Instruments. It serves as a specialized power management integrated circuit distinct from general-purpose switching controllers.
